US 2002/0184150 A1 Dec. 5, 2002 MOBILE BANKING SYSTEM [0001] THIS INVENTION relates to a banking system and in particular, to a mobile banking system. [0002] Commercial banks establish branch networks to expand their market coverage geographically and to com pete for market share, This is partlicularly evident in the retail banking business. To offer computerised services to their customers, banks normally install banking terminals for transaction processing in their branches. These banking terminals are connected to a mainframe computer at a data centre of the bank via a leased data line for on-line trans action processing. [0003] Establishing a branch network and the associated dedicated communcation network via a leased line is very expensive and may limit the ability of the bank to expand. A mobile banking system With its low operating costs and mobility could enhance the ability of a bank to render banking services over a Wide geographical area in order to expand the presence of the bank in the market-place. [0004] The present invention aims to provide a bank With a low cost but versatile mobile banking system. [0005] Accordingly, the invention provides a mobile bank ing system comprising a data processing centre for process ing banking transactions and a remote banking unit having one or more banking terminals operable by a user to effect banking transactions, in Which system the remote banking unit incorporates a Wireless communication device includ ing a mobile telephone by Which the remote banking unit communicates With the data processing centre over the associated Wireless communication network in order to perform the bank transactions. [0006] The remote banking unit is preferably a mobile banking unit installed on a vehicle, such as a car, bus or train and may be equipped With a group of banking service terminals, including terminals such as ATM s, passbook updating machines etc. The mobile banking unit and/or its individual banking service terminals, is or are equipped With mobile telephones With or Without modems and With or Without encryption devices. [0007] The data processing centre may be constituted by an existing mainframe computer of the bank s data centre, Which is correspondingly equipped With mobile telephones With or Without modems and With or Without encryption devices for data communication purposes. [0008] The mobile banking unit and/or its individual banking terminals can dial-up and connect via the Wireless mobile telephone network to the mainframe computer using the mobile telephones installed at both ends, thereby to perform banking transactions. [0009] A mobile banking system embodying the present invention applies mobile telephone technology and its Wire less communication network to banking operations and allows banks to offer their customers on-line banking trans action services at any location Which is Within reach of the mobile telephone network. [0010] The invention thus provides a bank With (a) the possibility of establishing mobile banking system and offer ing mobile banking services to its customers and (b) the ability to connect their banking terminals like ATMs, pass book updating machines, multi-media enquiry stations and the like to their mainframe computer in the data centre using mobile telephony ad its associated Wireless communication network, so as to provide banking services in any locations and/or on board transportation such as cars, buses and trains. [0011] The mobile banking system proposed by the present invention should offer the banks lower operating costs and possible expansion of market coverage geographi cally to include more remote and less densely populated areas of a country. In turn, the customers could expect to have easier access and more convenient banking services With longer operating hours and lower fees. The invention should, therefore, facilitate commercial activities as a Whole. [0012] In order that the invention may be more readily understood, embodiments thereof Will now be described, by Way of example, With reference to the accompanying draw ings, in Which: [0013] FIG. 1 is a schematic diagram giving an overview of a mobile banking system embodying the present inven tion: [0014] FIG. 2 is a block diagram of the structure of one embodiment of a mobile banking unit With centralised communication control via a computer server incorporated in the mobile banking unit; [0015] FIG. 3 is a block diagram of the structure of another embodiment of a mobile banking unit Without centralised control of communications; [0016] FIG. 4 is a block diagram of one example of a mobile banking unit incorporating a computer server; and [0017] FIG. 5 is a block diagram of an exemplary data centre of a bank. [0018] Referring to FIG. 1, the illustrated mobile banking system embodying the present invention comprises mobile banking units 1 and a banking data centre 2. Any number of mobile banking units 1 and data centres 2 may be employed in the system and the use of a single data centre 2 and two mobile banking units 1 as depicted in the drawing is for the purposes of illustration only. The mobile banking units 1 should have no geographical boundary and could be situated Within the same city, Within different cities or even Within different countries. [0019] The mobile banking unit 1 may take the form of a car, a bus or a train carrying on board banking terminals 1-3 Which are capable of performing on-line banking transac tions. Thus, an ATM installed in a car and capable of communicating With a mainframe computer 2-1 of the data centre 2 via a mobile telephone 1-22 is the simplest form of mobile banking unit. Customers can make a deposit, a WithdraWal, or an account transfer using the ATM as if it Were installed in the lobby of a conventional branch bank. [0020] Within the mobile banking unit 1, a computer server may be used to connect all the banking terminals 1-3, mobile telephones 1-22 and necessary peripherals, so that communication between the main frame computer 2-1 and the mobile banking unit 1 can be centralised Within the banking unit. Alternatively, the individual banking terminals 1-3 of the mobile banking unit may be equipped With their own mobile telephones 1-22 and other necessary peripher als, so as to communicate directly With the mainframe
US 2002/0184150 A1 Dec. 5, 2002 computer 2-1 When performing transactions. As another possibility, a banking unit 1 could employ a combination of these communication modes for different banking terminals 1-3. [0021] Within the context of the present invention, even if it is installed at a?xed site for a period of time instead of on a moving vehicle, the banking unit 1 is still considered to be a mobile banking unit, as long as it communicates With the bank s main frame computer 2-1 using a mobile telephone and the associated Wireless communication network. [0022] The data centre 2, and its mainframe computer 2-1, is normally located at the premises of the bank. It is the central data processing centre for all the banking terminals of the bank, including also the banking terminals 1-3 installed on the mobile banking unit 1. The banking termi nals of the branch offices continue to be connected via the dedicated leased line network, Whereas the terminals of the mobile banking unit 1 are connected to the data processing centre 2-1 by means of a mobile telephone 1-22, With or Without a modem and/or encryption device 1-21, and its Wireless communication network in order to process all kinds of banking transactions. [0023] A mobile banking system embodying the present invention thus enables a bank to establish a mobile banking presence. The mobile banking unit 1 can be installed on any means of transport or movable object and may, in special circumstances, be installed at a site. The connection of the mobile banking unit 1 to the mainframe computer 2-1 is through the Wireless mobile telephone communication net Work. Of course, the mobile banking unit 1 and/or its terminals 1-3 and the mainframe computer 2-1 must incor porate a mobile phone 1-22 With or Without a modem and/or an encryption device 1-21. [0024] To enhance the security of the data transmissions, encrypted data may be transmitted to and from the banking terminals 1-3 by separate message segments using different mobile telephone lines 6. On arrival, the data is recon structed and decrypted by an encryption/decryption device 2-22 of data centre 2 prior to processing by the mainframe computer 2-1 to ensure the highest degree of security. It is believed that using a Wireless network for data transmission in such an application is more secure and cost-effective. [0025] The Wireless communication network could be a satellite network or a microwave network or any other Wireless communication network. [0026] FIG. 2 is a block diagram, showing the compo nents of one embodiment of a mobile banking unit 1 having centralised control via an installed server. [0027] The exemplary mobile banking unit 1 of FIG. 2 consists of a moving object, such as a car 1-1, carrying on board a group of banking terminals 1-3, a Wireless commu nication device 1-2, With or Without a modem 1-21 and an encryption device 1-22. The individual banking terminals, such as ATM 1-36, cashier cheque issuing machine 1-35, telephone banking kiosk 1-34, passbook updating machine 1-39, tele-terminals 1-37 and alarm system 1-30, connect to the communication device 1-2 via computer server CPU 1-38. [0028] For self-service equipment, the customers of the bank can operate the machine for services as if they Were using the machines in the lobby of a bank, but behind the scenes data is transmitted via the Wireless communication network by means of the installed communication device 1-2. The tele-terminal 1-37 is to be operated as usual by the staff of the bank. [0029] The communication device 1-2, including the mobile telephones 1-22 With or Without the modem and encryption device 1-21, may be installed Within the mobile banking unit 1, as illustrated in FIG. 2, or outside the mobile banking unit 1, as illustrated in FIG. 1. [0030] FIG. 3 is a block diagram of the components of another embodiment of a mobile banking unit 1 Which, in this case, does not employ centralised communication con trol. [0031] The only difference between FIGS. 2 and 3 is that, in FIG. 3, a communication device 1-2 is incorporated in each banking terminal 1-3, so that each banking terminal is capable of communicating With the mainframe computer 2-1 directly in order to process a transaction. [0032] It is further envisaged that the mobile banking unit 1 may communicate With the data processing centre 2 using a combination of the two types of commuinication illus trated in FIGS. 2 and 3. For example, only the ATM 1-36 and the passbook updating machine 1-39 may have their own individual communication devices 1-2, and be able to communicate directly With the mainframe computer 2-1, Whereas the other banking terminals may be connected to a common communication device 1-2 via a computer server 1-38. [0033] In the event that there are bank staff on board the mobile banking unit 1, the staff may make use of the banking terminals to perform other banking services, such as the acceptance of cheque deposits and cheque WithdraWals etc. [0034] FIG. 4 shows another example of a mobile banking unit 1, in Which three ATMs 1-36 are connected to a single communication device 1-2 via a computer server 1-4. [0035] FIG. 5 illustrates schematically the structure of a data processing centre 2 of a bank. This centre comprises the mainframe computer 2-1 and mobile telephones 2-21, With or Without a modem and With or Without encryption device 2-22. The data processing centre 2 is connected to the mobile banking unit 1 using one or more mobile telephones 2-21 for data transmission via the mobile telephone Wireless com munication network in order to perform banking transac tions. [0036] The use of Wireless means of communication in a mobile banking system embodying the present invention is expected to enhance data communication security and to help reduce the communication costs of a bank. [0037] It Will be appreciated that the invention is simple and cost effective and should prove a bene?t both to the banks themselves and to their customers and the community. 1.
